FASTENING-INSERTING EEACHINE.

Application filed February 21, 1922. Serial No. 538.326.

To all whom it may concern.

Be it known that I, FRED L. li Lionmvzm, a citizen of the United States,residing at Beverly, in the county of Essex and State of Massachusetts,have invented certain 1m- 1'iroven'ients in Fastening-InsertingMachines, of which the following description, in connection wit-h theaccompanying drawings, is a specification, like'reference characters onthe drawings indicating like parts inthe several figures.

This invention relates to fastening inserting machines and moreparticularly to vorlr supports therefor which are operable to positionpieces of worir relatively to each other and to present the assembledwork in position for fastening inserting operations.

in one aspect the invention resides in a fastening inserting mechanismcomprising means for clinching the fastenings simultaneously with theirinsertion into the work and a work support mounted for universalmovement in a given plane to present the work over the clinching meansfor the insertion of fastenings spaced to secure together the portionsof the work.

In the illustrative machine the horn of the astening inserting mechanismcarries a work support movable horizontally in all directions to presentthe WOT; successively in a plurality of fastening inserting positions,means being provided for controlling the movement of the work supportrelatively to the horn.

The illustrated machine is designed more especially for securingtogether a counter and a tuck and for positioning these parts relativelyto each other as a preliminary to the operation of the fasteninginserting means. One of the difiiculties heretofore encountered inpositioning the tuck in the counter resides in the fact that. ifsufficient care werenot ex eri'ised, the tuck would rise upon theinnerronvexly curved surface of the counter to such an extent as to be dsplaced away from the flanges of the counter so that an imperfectarticle was not infrequently produced as a result of the parts heingsecured in the described relation. To overcome this difiiculty, there isprovided on the supporting member for the tucr a member or members forspacing the rear end of the tuck from the adjacent curved surface of thecounter, the said member or members serving also, in the illustrativeconstruction, as a gage or gages for locating the tuck along both itslongitudinal and transverse axes with respect to the fastening insertingmechanism.

As shown, gages are provided for rent end of the tuck and for thecounter,

I the the gages serving among other purposes to position the front endof the counter in a transverse direction with respect to the front endof the tuck. Conveniently the gages for the tuck and counter are mountedon a member which is movable with the supporting member for the tuck andcounter. Preferably the counter gages are so mounted as to besimultaneously adjustable to an equal extent in opposite directions,thereby providing for gaging operations on counters of different sizesso that all counters may be accurately positioned in a transversedirection with respect to their associated tucks.

Other important features of the invention, including combinations ofparts and details of construction, will be described in thespecification and pointed out in the appended claims.

In the drawings Figure l is a view in side elevation of a machineshowing one embodiment of the invention Fig. 2 is an enlarged detailview work support;

Fig. 8 is a plan view of the mechanism shown in Fig. 2; and

e is a bottom plan view of the counter with the tuck secured in place.

In the illustrating machine there is provided a fastening insertingmechanism 4. which is operative to insert fastenings into of the thework presented by the work support 6,

the said inserting mechanism being preferably, though not necessarily, astapling machine of the type shown in Patent No. 1.016.930, grantedFebruary 13, 1912, on application of N. H. Borden. As shown, the staplefastening mechanism a is provided with a horn 8 having at its upper enda fastening clinching block 10. For operating the horn in prop .r timedrelation to the fastening inserting mechanism, vided between the hornand the cam wheel 12 on the main shaft let, the said connectionscomprising a lever 16 pivoted at 18 in the frame of the machine andhaving an operative connection with the horn 8 as connect-ions are pro-7 indicated at 20. Passing through the rear under the pressure ofthe-spring 46.

end of the lever 16 is a rod 22 provided with a collar (not shown)between which and the washer 24 is a spring 26, the arrangement beingsuch that during the downward movement of the rod 22 the rear end of thelever 16 is depressed to carry the horn into yielding contact with thework thus allowing for variations in the thickness of the materialpresented for the insertion of fast-enings. It will. be understood thatthe spring 26 is of a strength sufficient to insure proper clinching ofthe fastenings through the cooperation of the clinching block 10 and thefastening driver at the lower end of the driver bar 28.

llixedly secured to the horn 8 is a bracket Ell) (Fig. 2) havingintegrally formed therewith or fixedly secured thereto a plate 32 havinga smooth supporting surface 34 over which the work support 6 is freelymovable.

.As shown, the work support comprises a base plate 35 and a post 36designed to sup port the rear end portions of the tuck t and counter c.Preferably and as shown, the actual work supporting surface is providedby a plate 88 having flanges, one of which is shown at 4.6, receivablein guide slots 42 in-the upper end of the post 86 so that'the plate 38is slidably mounted on the post. Positioned in a socket 4a in the upperend of the post 36 is'a spring 46 havingits'outer end connected to a pin48 rigid with the plate 38,*the arrangement being such that the plate 38is held yieldingly in the position. shown in Fig. 3 of the drawings, apin 50 being provided to move in aslot in the upper end of the post 36and :to contact with an end wall of the slot to limit the movement ofthe plate 38 A larried at the rear endof the plate 38 in fixed relationthereto are two lugs 52 which extend upwardly from the upper surface ofthe plate 38 a distance corresponding substantially to the thickness ofthe tucks ordinarily provided for work of this kind. These lugs 52 serveto engage the rear edge ofthe tuc-kand, in co-operation with the gage-54, to position thetuck and to center it with respect to the supportingplate38. For this reason the two lugs 52 are located at a considerabledistance each side of. the median line of the supporting plate 38 alongwhich the tuckis disposed. Furthen more, these lugs serve to space thecounter theproper distance from the rear edge of the tuck, an importantfeature as will herein after be m ore clearly explained.

At the-other end of the base plate 35 is apost 56 which may beintegrally formed with the base plate or a. separate member 'fixedlyattached thereto. 'Rotatably supported on the post 56 is a pair ofgage'memhers 58 and 60 adapted 'to enter the forward end of the counterto position the counter in a transverse direction with respect to theforward end of the tuck. In the illustrated construction, the member 60has a forked extension 62 which is located on the other Side of thesupporting post 56. Similarly the member 58 has a forked extension 64:located below the first mentioned forked extension, the slots 66 and 68,re spectively in each forked extension, extending at a considerableangle to each other and with respect to the longitudinal axis of'itsrespective gage member for a purpose that willv be made clear as thedescription proceeds. 7 Located below the gage members on the post 56 isa slide 70 which straddles the post and is adjustable thereon, theadjustment being secured through the rotation of the adjusting member 72which is screwthreaded into thepost 56. Carried fixedly by the adjustingmember 72 is a collar 74 which is located within a slottedextension 76of the slide70; Extending upwardly from the upper surface of the slide'70 is a pin or stud 78 which carries an anti-friction roll 80. Asshown, the stud 78 with its roller extendsinto both of the slots 66 and68, respectively, of the extensions 62 and 64 on the gage members 60--and 58.

Upon turning the knurled handle 82 of the adjusting member 72, inencounter-clockwise direction in Fig. 2, the stud 7 8 is moved away fromthe post 56 and toward the outer end of bothof the slots 66 and 68,thereby moving the gage members 58 and 60 simultaneously away from eachother. Since the gage members 58 and 60 are moved to an equal extent inopposite. directions they will cooperate in maintaining the counter inproper position with respect to the tuck irrespective ofthe amount ofadjustment to, accommodate allfof'the various sizes of counterswhich-may be presented for fastening inserting operations. Secured tothe upper end of the post 56 is a block SLhaving in its iu'iper'surfacea slot or groove in which is slidably mountedthe gage-member5-flmentioned in the early part of this description: Preferably the gageoalis provided with an elongated slot so that it may be adjusted in adirection toward and from placed in positioning the tuck fasteninginserting mechanism.

- longitudinal axis of the base plat construction, solely for thepurpose of providing gage members for both the tuck and the counter.

In order that the work support may accommodate tucks and counters ofvarious sizes, the post 36 is made adjustable upon the base plate 35. Asillustrated the base plate is provided with a slot 9 preferablydove-tailed to receive the lower end of the post and to assist inretaining the post in its position on the base plate, it beingunderstood that the post is slidable along the slot to various positionsof adjustment. For securing the post in adjusted position there provideda bolt 96 (Fig. 2) having a head 98 receivable.in a T-shaped slot 100 inthe lower face of the post 36. As shown the shank of the bolt 96 isscrew-threaded eXteriorly to fit into a screw-threaded socket in thebolt or adjusting member 102 which is provided with a collar 10 iadapted to engage the under surface of the base plate 35. It will beobvious that when the bolt 102 is rotated in the proper direction itwill draw the bolt 96 downwardly, thus firmly clamping the post 36 uponthe base plate through the co-operation of the head 98 on the bolt 96with the collar 10% on the adj usting member 102.

In order that the Work support 6 may freely move with respect to thehorn 8, the base plate 35 is provided witha relatively large opening 106in its middle portion surrounding the post 8. By struction, the plate 35may move in slidable engagement with the surface 34-. a considerabledistance from right to left in Fig. 2 and also in a directiontransversely of the for the purpose of determining the extent ofmovement along the longitudinal axis of the base plate there is provideda controlling or limiting member 110 secured to the lower surface of thesupporting plate 82. As shown, the member 110 is provided with slots 112(Fig. or the reception of screws 111i. (Fig. 2) by which the plate maybe secured adjustably in fixed position. Preferably the plate 110comprises two arms 110 and 118 spaced from each other and extendingpractically across an opening 120 in the plate 32. When the work support6 is moved from right to left or in reversed direction in Fig. 2, thebolt 102 will et'entually come into contact with oneof the arn'is 116,118 and thus the bolt 102 in co-operation with the arms 116, 118 on theplate 110'serves as a limiting means for controlling the extent ofmovement of the work support in the directions referred to. The. bolt102 also serves to limit the movement of the work support in a directionat right angles to that described by reason of its engagement withthewalls of the opening 120 in the plate In the operations of. securingacounter to reason of this cona tuck with the aid of the work supportshown in the illustrated machine, a tuck is first placed in positionwith its front end in engagement with the gage 54 and resting upon theclinching plate 10, the rear end of the tuck being supported upon theplate 38. The operator iseXpected to exercise reasonable care inpositioning the trick sothat it will extend substantially along eachside of a longitudinal line passing through the center of the plate 38and through the center of the clinching plate 10. He will be assisted inthis operation by reason of the presence of the two lugs which arelocated near but not in contact with the rear curved edge of the tuck.In other words, the post 30 with the supporting plate 38 are so adjustedwhen a tuck ot a given size is to be operated upon, that the lugs 52will be spaced from the gage a distance slightly greater than the lengthof the tuck. Hence when the counter 0 is placed over the tuck t-withitsinturned flanges c resting on the tuck and the whole moved to the leftin Fig. 2, the lugs 52 engage with the convexly rounded end of the tuckand help to center it propcrly on its support. Furthermore, the lugs 52will serve to space the counter, and especially'its inner curvedsurface, away from the adjacent edge of the tuck. Because of the factthat the inner surface of the counter 0 just below the flanges c iscurved abruptly away from the flange. or flanges 0 there is a tendencycurved wall of the counter causing it to ride up on the curved surfaceand hence the lugs 52 serve a useful purpose in spacing the counterproperly with respect to the tuck.

After the counter and tuck have been placed upon the work support andshoved over toward the left in Fig. 2, during which operation the plate38 is moved against its spring 46 to enable the lugs 52 to contact withthe rear convex edge of the tuck, the whole support 6 is positioned (l?for the first fastening to be inserted. Subsequently the support isshoved to the left in Figs. 2 and 3 a distance corresponding to thespace between the arms: 116 and 118 on the limiting plate 110 and intoposition for the insertion of the second *t'asteningon thesame side orflange portion of the counter. thd'isequently the work support. isshifted in a direction transverse to the longitudinal axis of the baseplate 35 so as to insert the first staple in the opposite flange thenthe work support is shifted toward the right bringing the bolt 102 upagainst the arm 118 in which position the fourth and last staple isinserted. Preferably the work support is then shifted transversely ofthe slot or opening 120 to bring it to initial position, the work isremoved .and fresh work substituted and then the operations abovedescribed repeated to secure another tuck and counter in their deto fitthe tuck too closely to the 1.
